Description

Technical Field

[0001] This invention relates to the field of drilling technology, specifically to a parallel-propulsion isolation drilling device and its application in building construction. Background Technology

[0002] During the construction of bridges, tunnels, slopes, and other projects, it is necessary to drill holes on the side to facilitate the subsequent installation of signs and other equipment. In the aforementioned construction projects, there are situations where drilling operations need to be carried out in relatively narrow areas. If operators enter these areas to work, the limited space will increase the difficulty of operation. At the same time, the installation and setting of signs is even more important in the curved areas of bridges, tunnels, and slopes.

[0003] Because it is located in a curved area, the side curb protrusions are in a spiral tilt. In order to improve the installation effect of the sign, the construction personnel need to adjust the angle of the electric drill. The adjustment angle includes vertical and horizontal adjustment. However, due to the construction location, the construction personnel are affected by factors such as limited space, the suspended working surface, and inconvenient power supply, making it difficult to quickly adjust the electric drill angle. This makes the operation difficult and affects the installation accuracy and indication effect of the subsequent sign. Summary of the Invention

[0004] The purpose of this invention is to provide a parallel-propulsion-based isolated drilling device and its application in building construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a parallel-propulsion isolation drilling device, comprising: a frame structure on which a receiving plate is rotatably mounted; a traction assembly slidably disposed on the frame structure, the traction assembly being able to change the pitch angle of the receiving plate when moving along the length direction of the frame structure; a follower plate parallel to the receiving plate, on which an electric drill capable of moving along its length direction is disposed; a rotation assembly disposed on the frame structure and connected to the follower plate, the rotation assembly being able to change the deflection angle of the follower plate; and an adjustment assembly mounted on the frame structure and connecting the traction assembly and the rotation assembly, the adjustment assembly including a threaded adjustment structure and an operating rod, wherein a locking tongue disposed on the operating rod cooperates with two sets of locking grooves disposed on the threaded adjustment structure, enabling control of the movement of the traction assembly and the rotation assembly respectively.

[0006] As a further embodiment of the present invention: the threaded adjustment structure includes two sets of coaxial hollow threaded rods rotatably mounted on the frame structure, the locking groove is disposed at one end opposite to the two sets of hollow threaded rods, and the operating rod passes through the hollow threaded rods; the threaded adjustment structure also includes a first threaded sleeve and a second threaded sleeve that are threadedly engaged with the two sets of hollow threaded rods, the first threaded sleeve being connected to the pulling assembly, and the second threaded sleeve being connected to the rotating assembly.

[0007] As a further embodiment of the present invention: the traction assembly includes a sliding connector slidably mounted on the frame structure and connected to the first threaded sleeve, a lifting rod capable of moving in a vertical direction is slidably mounted on the sliding connector, a fitting shaft is rotatably mounted on the lifting rod, and the fitting shaft is rolledly connected to a fitting groove provided on the side of the receiving plate; the traction assembly also includes a guide structure provided on the lifting rod and the frame structure, the guide structure being capable of driving the lifting rod to change height relative to the frame structure.

[0008] As a further embodiment of the present invention: the guide structure includes a convex shaft rotatably mounted on the lifting rod and a side plate fixedly mounted on the frame structure, the side plate being provided with an inclined groove, and the convex shaft being able to roll within the side plate.

[0009] As a further embodiment of the present invention: the rotating assembly includes a rotating rod rotatably connected to the frame structure, the lower end of the rotating rod being connected to the follower plate, and a lifting sleeve slidably sleeved on the rotating rod, a hinge rod rotatably mounted on the lifting sleeve, and the end of the hinge rod away from the lifting sleeve being connected to the second threaded sleeve; the rotating assembly also includes a keyway assembly disposed between the lifting sleeve and the rotating rod, the keyway assembly being able to drive the rotating rod to rotate when the lifting sleeve performs a lifting action.

[0010] As a further embodiment of the present invention: the keyway assembly includes a guide shaft disposed on the inner wall of the lifting sleeve and a spiral groove disposed on the circumferential side wall of the rotating rod, wherein the guide shaft and the spiral groove are slidably engaged.

[0011] As a further embodiment of the present invention: two sets of grooved wheels are rotatably mounted on the follower plate, and the grooved wheels can roll in the arc-shaped grooves provided on the receiving plate; the follower plate is also provided with a sliding groove along its length, and a slider is slidably mounted in the sliding groove, and the moving frame connected to the slider is connected to the electric drill.

[0012] As a further embodiment of the present invention: a traction frame is slidably mounted on the frame structure, and a connecting groove is provided on the traction frame. The connecting groove cooperates with a connecting shaft rotatably mounted on the follower plate, so as to drive the electric drill to move when the traction frame moves.

[0013] The application of the parallel-propulsion isolation drilling device in building construction, as described above.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: By using the traction and rotation components, the pitch and tilt angles of the electric drill can be adjusted separately, ensuring the stability of the tilt angle when adjusting the pitch angle, and the stability of the pitch angle when adjusting the tilt angle. This results in a stable, controllable orientation of the electric drill, reducing adjustment difficulty and improving drilling accuracy, while also reducing the complexity of subsequent equipment installation. Furthermore, the traction frame and connecting shaft allow construction workers to stand on the bridge, tunnel, or slope when drilling into protruding curbs in curved areas of bridges, tunnels, and slopes. It eliminates the need to access the outside of bridges, tunnels, and slopes, avoiding operational difficulties caused by confined spaces. Through the adjustable components, the two sets of hollow threaded rods can be driven to rotate independently during the insertion and removal of the operating rod, allowing for individual control of the pulling and rotating components. Furthermore, the hollow threaded rods are connected to the first and second threaded sleeves via threaded connections, which are self-locking. This ensures that when the locking tongue separates from one set of hollow threaded rods, the connected first or second threaded sleeve remains locked, resulting in better stability of the pitch angle of the receiving plate and the deflection angle of the follower plate after adjustment, thus improving drilling quality.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0029] Please see Figures 1-11 In this embodiment of the invention, the parallel propulsion-based isolation drilling device includes: a frame structure 1, a traction assembly, a follower plate 13, a rotation assembly, and an adjustment assembly.

[0030] The adjustment assembly is mounted on the frame structure 1 and connects the pulling assembly and the rotating assembly. The adjustment assembly includes a threaded adjustment structure and an operating rod 6. A locking tongue 601 on the operating rod 6 cooperates with two sets of locking grooves 19 on the threaded adjustment structure, which can control the movement of the pulling assembly and the rotating assembly respectively. The threaded adjustment structure includes two sets of coaxial hollow threaded rods 8 rotatably mounted on the frame structure 1. The locking grooves 19 are located at opposite ends of the two sets of hollow threaded rods 8, and the operating rod 6 passes through the hollow threaded rods 8. Specifically, the locking grooves 19 face towards... Two sets of inclined surfaces are provided at one end of the opening, and the inclined surfaces on opposite sides of the two sets of locking grooves 19 intersect, that is, the two sets of inclined surfaces form a spike. The end of the locking tongue 601 facing the locking groove 19 is also provided with a spike. When the locking tongue 601 is inserted into the locking groove 19, the inclined surfaces can guide the locking tongue 601 into the locking groove 19. Thus, the locking tongue 601 can be inserted into the corresponding locking groove 19 by pulling and inserting the operating rod 6. When the operating rod 6 is rotated, it can drive the two sets of hollow threaded rods 8 to rotate, thereby driving the pulling assembly and the rotating assembly to move, realizing the step-by-step control of the pulling assembly and the rotating assembly.

[0031] It should be noted that the aforementioned operating lever 6 and the frame structure 1 can slide and rotate relative to each other, and a damping sleeve is provided at the connection between the operating lever 6 and the frame structure 1 to improve the stability of the operating lever 6 after insertion and removal. At the same time, the inner diameter of the two sets of hollow threaded rods 8 is larger than the outer diameter of the operating lever 6 to avoid the hollow threaded rod 8 rotating when the locking tongue 601 is not engaged with the locking groove 19 due to friction between the operating lever 6 and the inner wall of the hollow threaded rod 8 during the rotation of the operating lever 6.

[0032] The threaded adjustment structure also includes a first threaded sleeve 5 and a second threaded sleeve 9 that are threadedly engaged with the two sets of hollow threaded rods 8. The first threaded sleeve 5 is connected to the pulling assembly, and the second threaded sleeve 9 is connected to the rotating assembly. It is worth noting that, in this embodiment, in order to improve the moving stability of the second threaded sleeve 9, a guide can be provided on the frame structure 1. The guide maintains the axial stability of the second threaded sleeve 9 by slidingly connecting with it, thereby preventing the second threaded sleeve 9 from rotating along with the hollow threaded rods 8.

[0033] By inserting and removing the operating lever 6, the locking tongue 601 can be inserted into the corresponding locking groove 19. Rotating the operating lever 6 causes the two sets of hollow threaded rods 8 to rotate respectively. When one set of hollow threaded rods 8 rotates, the first threaded sleeve 5, which is threadedly engaged with it, moves along the length of the hollow threaded rod 8, thereby driving the pulling assembly to adjust the pitch angle of the receiving plate 2. When the other set of hollow threaded rods 8 rotates, the second threaded sleeve 9, which is threadedly engaged with it, moves along the length of the hollow threaded rod 8, thereby driving the rotating assembly to change the deflection angle of the follower plate 13. With the above configuration, during the insertion and removal of the operating lever 6 and the rotation of the operating lever 6, the two sets of hollow threaded rods 8 can be driven to rotate separately, thereby enabling individual control of the pulling and rotating components. Furthermore, the hollow threaded rods 8 are connected to the first threaded sleeve 5 and the second threaded sleeve 9 by threads, and the threaded connection has self-locking properties. This ensures that when the locking tongue 601 is separated from one of the hollow threaded rods 8, the first threaded sleeve 5 or the second threaded sleeve 9 connected to it remains locked. As a result, the pitch angle of the receiving plate 2 and the deflection angle of the follower plate 13 can have better stability after adjustment, thereby improving the drilling quality.

[0034] Please see Figures 5-6 The frame structure 1 is rotatably mounted with a support plate 2. The frame structure 1 consists of two sets of parallel plates and a connecting plate perpendicular to the parallel plates. The end of the connecting plate away from the parallel plates is rotatably connected to the support plate 2. Furthermore, the end of the parallel plates away from the connecting plates is also provided with two sets of connecting plates. The two sets of connecting plates and the parallel plates form a U-shaped structure. Multiple sets of rollers are rotatably mounted on the inner side of the U-shaped structure. In use, the U-shaped structure is clamped onto the curb protrusion of the bridge, tunnel, or slope, so that the rollers abut against the curb protrusion, thereby improving the stability of the frame structure 1 during drilling. At the same time, after drilling is completed, the frame structure 1 can be pulled along the length direction of the curb protrusion, thereby reducing the difficulty of moving the frame structure 1.

[0035] It should be noted that, considering the different inner angles and widths of the curb protrusions on bridges, tunnels, and slopes, the connecting plate away from the connecting plate can also be set to be detachably connected to the parallel plate, thereby matching different types of bridges, tunnels, or slopes.

[0036] The traction assembly is slidably mounted on the frame structure 1. When the traction assembly moves along the length of the frame structure 1, it can change the pitch angle of the receiving plate 2. The traction assembly includes a sliding connector 4 slidably mounted on the frame structure 1 and connected to the first threaded sleeve 5. A lifting rod 3 that can move in the vertical direction is slidably mounted on the sliding connector 4. The sliding connector 4 can slide along the length of the parallel plate, while the lifting rod 3 can slide perpendicular to the parallel plate relative to the sliding connector 4, that is, the lifting rod 3 can rise and fall vertically relative to the parallel plate.

[0037] A fitting shaft 302 is rotatably mounted on the lifting rod 3, and the fitting shaft 302 is rotatably connected to the fitting groove 202 provided on the side of the receiving plate 2.

[0038] In the initial state, the fitting shaft 302 is located in the middle of the fitting groove 202. At this time, the receiving plate 2 is parallel to the parallel plate. When the sliding connector 4 slides and the lifting rod 3 moves up and down relative to the parallel plate, the lifting rod 3 can move horizontally and vertically. During this process, the fitting shaft 302 can move towards both ends along the length of the fitting groove 202. At the same time, the fitting shaft 302 and the fitting groove 202 cooperate to pull the receiving plate 2 when the lifting rod 3 moves vertically, so that the receiving plate 2 can deflect around its rotation center and change the pitch angle of the receiving plate 2. The pitch angle of the receiving plate 2 is in the range of -10° to 10°.

[0039] The traction assembly also includes a guide structure disposed on the lifting rod 3 and the frame structure 1. The guide structure can drive the lifting rod 3 to change height relative to the frame structure 1. The guide structure includes a convex shaft 301 rotatably mounted on the lifting rod 3 and a side plate 7 fixedly mounted on the frame structure 1. The side plate 7 is provided with an inclined groove 701, and the convex shaft 301 can roll within the side plate 7. The follower plate 13 is parallel to the receiving plate 2, and an electric drill 16 that can move along its length direction is disposed on the follower plate 13.

[0040] Specifically, when the first threaded sleeve 5 drives the sliding connector 4 to move, the sliding connector 4 can drive the lifting rod 3 to move perpendicular to the parallel plate. In the initial state, the convex shaft 301 is in the middle position of the inclined groove 701, so that when the lifting rod 3 moves along the length direction of the parallel plate, the convex shaft 301 can move along the inclined groove 701. At this time, the lifting rod 3 can move along the length direction of the parallel plate while moving along the length direction of the parallel plate. Through the cooperation of the fitting shaft 302 and the fitting groove 202, the lifting and lowering of the receiving plate 2 is realized to change the pitch angle of the receiving plate 2. Since the follower plate 13 is parallel to the receiving plate 2, the pitch angle of the electric drill 16 connected to the follower plate 13 will also change accordingly. The change in the pitch angle of the electric drill 16 ensures the construction angle of the electric drill 16 when working on the curb protrusions in the curved area of ​​bridges, tunnels, and slopes, and ensures that the corresponding equipment is easier to install after drilling.

[0041] Please see Figure 3 , Figures 7-9 The rotating assembly is mounted on the frame structure 1 and connected to the follower plate 13. The rotating assembly can change the deflection angle of the follower plate 13. The rotating assembly includes a rotating rod 12 rotatably connected to the frame structure 1. The lower end of the rotating rod 12 is connected to the follower plate 13. When the projection of the follower plate 13 along its length on the horizontal plane is parallel to the projection of the parallel plate along its length on the horizontal plane, the rotation axis of the follower plate 13 is coaxial with the rotation axis of the receiving plate 2. At this time, when the rotating rod 12 rotates and changes the pitch angle, the follower plate 13 can rotate synchronously without interference. It should be emphasized that... When adjusting the pitch angle of the receiving plate 2 and the deflection angle of the follower plate 13, the adjustment should be carried out in the order of first adjusting the pitch angle of the receiving plate 2 and then adjusting the deflection angle of the follower plate 13. In the initial state, the follower plate 13 is parallel to the length direction of the parallel plate. At this time, the rotation axis of the follower plate 13 is coaxial with the rotation axis of the receiving plate 2. This allows the pitch angle of the follower plate 13 to change when the pitch angle of the receiving plate 2 changes, and then the deflection angle of the follower plate 13 is adjusted. This prevents the pitch angle adjustment of the receiving plate 2 from being obstructed due to the non-coaxiality of the rotation axis of the follower plate 13 and the rotation axis of the receiving plate 2 after the deflection angle of the follower plate 13 changes.

[0042] A lifting sleeve 11 is slidably sleeved on the rotating rod 12. A hinge rod 10 is rotatably mounted on the lifting sleeve 11. The end of the hinge rod 10 away from the lifting sleeve 11 is connected to the second threaded sleeve 9. It should also be noted that the guide can prevent the second threaded sleeve 9 from rotating with the hollow threaded rod 8, thus preventing the hinge rod 10 from bearing torque. However, when the lifting sleeve 11 moves and causes the rotating rod 12 to rotate, the lifting sleeve 11 will also have a tendency to rotate. Therefore, a guide can be provided on the frame structure 1. By sliding the guide with the lifting sleeve 11, the rotation of the lifting sleeve 11 can be limited. This can improve the correlation between the lifting distance of the lifting sleeve 11 and the rotation degree of the rotating rod 12, and also improve the control accuracy.

[0043] The rotating assembly also includes a keyway assembly disposed between the lifting sleeve 11 and the rotating rod 12. The keyway assembly can drive the rotating rod 12 to rotate when the lifting sleeve 11 performs a lifting action. The keyway assembly includes a guide shaft 1101 disposed on the inner wall of the lifting sleeve 11 and a spiral groove 1201 disposed on the circumferential side wall of the rotating rod 12. The guide shaft 1101 and the spiral groove 1201 are slidably engaged.

[0044] In the initial state, the guide shaft 1101 is in the middle position of the spiral groove 1201. When the second threaded sleeve 9 rotates with the hollow threaded rod 8 connected to it, it can move along the length direction of the hollow threaded rod 8. At this time, the second threaded sleeve 9 can drive the lifting sleeve 11 to move along the length direction of the rotating rod 12 through the hinge rod 10. With the cooperation of the guide shaft 1101 and the spiral groove 1201, the rotating rod 12 is driven to rotate. At this time, the rotating rod 12 can drive the follower plate 13 to deflect, thereby changing the deflection angle of the electric drill 16. In this state, since the pitch angle and deflection angle of the electric drill 16 are controlled, the positional accuracy during drilling is improved.

[0045] With the above settings, the pitch angle and tilt angle of the electric drill 16 can be adjusted separately, while ensuring the stability of its tilt angle when adjusting the pitch angle and the stability of its pitch angle when adjusting the tilt angle. This makes the orientation of the electric drill 16 stable under controllable conditions, which can reduce the difficulty of adjustment, improve drilling accuracy, and reduce the complexity of subsequent equipment installation.

[0046] Please see Figure 1 , Figure 6 , Figure 8 , Figure 11Two sets of grooved wheels 14 are rotatably mounted on the follower plate 13. The grooved wheels 14 can roll in the arc groove 201 set on the receiving plate 2. The angle between the two ends of the arc groove 201 and the reference plane is -8° to 8° with the length direction of the receiving plate 2 as the reference plane. That is, the adjustable range of the deflection angle of the follower plate 13 is -8° to 8°.

[0047] When in use, the grooved wheel 14 can roll along the arc groove 201, so that with the cooperation of the grooved wheel 14 and the arc groove 201, the receiving plate 2 has the traction of the follower plate 13, thereby ensuring the stable parallel state of the follower plate 13 and the receiving plate 2, and improving the stability of the electric drill 16 when moving relative to the follower plate 13.

[0048] The follower plate 13 is also provided with a sliding groove 1301 along its length. A slider 1501 is slidably installed in the sliding groove 1301. The movable frame 15 connected to the slider 1501 is connected to the electric drill 16. A traction frame 18 is slidably installed on the frame structure 1. Specifically, the traction frame 18 is slidably installed through the frame structure 1. The traction frame 18 is provided with a connecting groove 1801. The connecting groove 1801 cooperates with the connecting shaft 17 rotatably installed on the follower plate 13, so that the electric drill 16 can be driven to move when the traction frame 18 moves.

[0049] It should also be noted that the width of the connecting groove 1801 is greater than the diameter of the connecting shaft 17. The purpose of this is that if the width of the connecting groove 1801 is equivalent to the diameter of the connecting shaft 17, then when the connecting shaft 17 changes pitch and deflection angles following the follower plate 13, interference will occur between the connecting groove 1801 and the connecting shaft 17.

[0050] In this embodiment, when the pitch and yaw angles of the electric drill 16 are adjusted, by pulling the traction frame 18, the moving frame 15 can be driven to move along the length direction of the follower plate 13 when the connecting shaft 17 abuts against one side wall of the connecting groove 1801, thereby performing the drilling action. This allows construction personnel to stand on the bridge, tunnel, or slope to carry out construction when drilling holes in the curb protrusions in the curved areas of bridges, tunnels, and slopes, without having to enter the outside of the bridge, tunnel, or slope, thus avoiding the difficulties in operation caused by the narrow space and the risk of high-altitude operation.
